smoke detector battery

A beeping smoke detector is most often a low battery, dusty sensor, or a unit that’s reached its 10-year replacement age. In LA homes with recent water damage or wildfire smoke exposure, false alarms can also signal a damaged unit needing replacement. This guide covers every beep pattern, what each means, how to stop it safely, and when California code requires replacement. Questions about fire damage? Call (818) 336-1800.
